3D AlOOH/Fe Micro/Nanostructures: Facile Synthesis, Characterization and Application for Arsenic Removal

Abstract:

Novel 3D AlOOH/Fe micro/nanostructures were successfully synthesized by the reaction of Al/Fe binary metallic nanoparticles with water at 60°C and under atmospheric pressure. Al/Fe binary metallic nanopowder was produced by the method of simultaneous electric explosion of twisted aluminum and iron wires in an argon atmosphere. Produced 3D AlOOH/Fe structures were characterized by TEM, SEM, XRD, EDX, BET, and adsorption capacity towards As (V). The hard framework consisting of both the boehmite nanosheets and the nanosheets enriched with iron provides a large available surface and prevents the aggregation of the micro/nanostructures. The high adsorption capacity of 42 mg g^-1 As (V) under static conditions allows obtained 3D AlOOH/Fe micro/nanostructures to be a promising material for the removal of arsenic from contaminated drinking water.
